Answer: x = log10(21875)/log10(3)

Step-by-step explanation:

3x=21875

3 to the power of x equals 21875

Take the log of both sides

log10(3x)=log10(21875)

Rewrite the left side of the equation using the rule for the log of a power

x•log10(3)=log10(21875)

Then, Isolate the variable x by dividing both sides by the constant term log10(3)

x = log10(21875)/log10(3)

Solve the following system of equations.express your answer as an ordered pair in the format (a,b) with no spaces between the nu
frosja888 [35]

Answer: (3,2)

Step-by-step explanation:

For this set of system of equations, let's use elimination method to find x and y. Let's eliminate y first. In order to do so, the y values have to be the same. Therefore, you multiply the top equation by 3 and the bottom equation by 4.

9x+12y=51

-16x-12y=-72

Now, we can add the 2 equations together for the y to cancel out.

-7x=-21

x=3

Since we know x, we can plug it into any of the equations to find y.

3(3)+4y=17

9+4y=17

4y=8

y=2

With out x and y value, we can put them into an ordered pair. (3,2)

If the revenue for the week is $2000 and the labor cost consists of two workers earning eight dollars per hour who work 40 hours
arsen [322]
To find the cost of labor for one worker, you multiply the wage by the number of hours worked. 

40 * 8 = 320

Because there are two workers, now you double it. 

320 * 2 = 640

To find the percentage of the revenue that this is, you do the labor cost divided by the revenue. 

640 / 2000 = 0.32

Move the decimal two places to the right to get the percentage. 

0.32 = 32%

The labor cost is 32% of the revenue.
